In the EV3 programming environment, it is possible to start multiple threads. For example, you want two motors to run simultaneously and when both motors are finished, you want to play a sound. But there is no default mechanism in the programming environment to continue with the main thread when the second has also finished. In the example below, the “Ready” sound is played too early if motor A finishes before motor B is finished.

So, not just a typical locker as can be found in a gym or school. But what then … a sliding door? A garage door? A bus door?
